We study a dynamic economy endowed with a sequence of overlapping generations of consumers and production processes, and where productive assets are illiquid and consumption preferences are subject to uninsurable demand for liquidity. We characterize the steady states that can be achieved with alternative financial systems. We show that infinitely lived financial intermediaries offering a liability with age-dependent restrictions may implement a social optimum with full insurance. If, instead, they offer anonymous, unrestricted contracts, then only second-best consumption allocations with partial insurance obtain. We also examine the consumption allocations available when agents can trade shares in competitive stock markets. While allowing for trade across generations may or may not improve upon generational autarky, we show that this competitive equilibrium is not a social optimum, and is dominated by a system of infinitely lived, unrestricted intermediaries.

In 1991, the rate of inflation in the Czech Republic, Hungary and Poland was 57%, 35% and 70%. At the end of 2001, it was everywhere below 8%. We set up a small structural macro model of these three economies to account for the process of disinflation. We show that a simple macro model, with forward-looking inflation and exchange rate expectations, can adequately characterize the relationship between the output gap, inflation, the real interest rate and the exchange rate during this period. This model allows us to assess the relative importance of the interest rate and exchange rate channels in determining the path of disinflation.
